| Abstract: | The paper studied the colouring reaction of cadmium and CrystalViolet-Nitroso R Salt by Spectrophotometry.The experimental result showed that the blue trinary complex has been formed among rare H 2SO 4 solution.The λ max =630nm,CdRCV=136, ε =6.1×10 4L·mol -1 ·cm -1 .And used this way determined cadmium in slopping of Paper Mill,Qiqihar,the recoveries are between 98.3%-101.6%. |
